    摘要： A method and apparatus for providing barbed strap coils without a core by means of a ring coiling device (50) that has no winder provides a single clamping device (96), whereby the coiling is interrupted for the placement of a clamp. A guide device (11B) is arranged in front of the clamping device (6) by means of which two strap sections separated by one loop can be pushed toward the clamping device (96) by means of a strap feeding device (38). The two coils are guided outside the interruption in the coiling synchronously and in like phase through the location where the clamps are applied, by a synchronization device (60) in the clamping device (96) which engages slip-free in the two strap sections by means of a member (62). A counter (80) that counts the member movements between two successive clamping steps is coupled with member (162).

    摘要： For the reduction of the work function of the electrodes, gas discharge arresters contain an activator which contains, for example, an alkali metal or nickel. Getter materials, for example barium aluminum, serve the purpose of gettering of gases which can arise in the surge voltage arrester during manufacture or during operation. With these substances, the spreads of the minium operating voltage can be maintained small as long as the activator is only moderately heated. For high loads, the activator contains an alkali metal or nickel and, in addition, barium aluminum, whereby tungsten and/or molybdenum is present as the additional substance. An activator of this type guarantees constant values of the minumum operating voltage and a narrow spread of these values even after a high electrical and thermal load. A frequent switching of the maximally permissible current is possible without an interfering alteration of the electrical characteristics.
